Methyl 2-(pyrazin-2-ylcarbon­yl)hydrazinecarbodithio­ate, C7H8N4OS2, (E1), N′-[bis­(methyl­sulfan­yl)methyl­idene]pyrazine-2-carbohydrazide, C8H10N4OS2, (F1), N′-[bis(methyl­sulfan­yl)methyl­idene]-6-meth­oxy­pyrazine-2-carbohydrazide, C9H12N4O2S2, (F2), and methyl 1-methyl-2-(pyrazin-2-ylcarbon­yl)hydrazinecarbodithio­ate, C8H10N4OS2, (G1), can be con­sid­ered as derivatives of classical (thio)­amide-type tuber­culo­statics, and all are moderately active against Mycobacterium tuberculosis. This study was undertaken in a search for relationships between activity and specific intra­molecular inter­actions, especially conjugations and hydrogen-bond contacts, and the mol­ecular structures were compared with respective amine analogues, also active against the pathogen. Despite the differences between the amine and carbonyl groups with opposite functions in the hydrogen bond, the two types of structure show a surprisingly similar planar geometry, mostly due to the conjugations aided by the bifurcated intra­molecular hydrogen-bond contact between the N—H group of the central hydrazide group as donor and a pyrazine N atom and an S atom of the dithio function as acceptors. Planarity was suggested to be crucial for the tuberculostatic activity of these compounds. The N-methyl­ated derivative (G1) showed a significant twist at the N—N bond [torsion angle = −121.9 (3)°] due to the methyl substitution, which precludes an intra­molecular N—H...S contact and the planarity of the whole mol­ecule. Nonetheless, the compound shows moderate tuberculostatic activity.

Comment top

For many years, tuberculosis was considered a disease of the past, limited mainly to poor countries which could not afford expensive treatment, and this led to decreased interest in searching for more effective drugs. However, a more recent rise in mortality rates and the spread of the disease in developed countries, attributed to the emergence of multi-drug resistant strains, have changed this attitude. The search for new lead compounds was continued by several groups (Foks et al., 2000; Gobis, Foks, Zwolska & Augustynowicz-Kopeć, 2006; Gobis, Foks, Żuralska & Kędzia, 2006), who synthesized several chemical classes of potential antituberculostatic agents, in particular those containing either pyrazin-2-yl-carbonimidoyldithiocarbazic acid esters, heteroaroylcarbonimidoyldithiocarbazate or heteroaroyldithiocarbazate systems. The compounds comprise molecular features present in the classical amide-type tuberculostatics, in particular heteroaroyl, amide and thioacid functions, such as in pyrazinamid, isoniazid and ethionamid (see first scheme), which act through the formation of a covalent adduct with nicotinamide adenine dinucleotide (Wang et al., 2007).

Our earlier crystallographic studies of selected representatives of 3-[amino(pyrazin-2-yl)methylidene]-2-methylthiocarbazic acid esters (see second scheme, formula A) showed that all of them maintained planarity of the whole molecule, except for the terminal aliphatic substituents (Główka et al., 2005; Olczak et al., 2007; Orlewska et al., 2001). The planarity observed in these structures was caused by extensive conjugation aided by a bifurcated intramolecular hydrogen-bond contact between the protonated atom N3 as a donor and two acceptors. One acceptor was a negatively charged S atom and the other an ortho-positioned N atom of a pyrazine or pyridine ring on the other side of the donor (second scheme, formula A). The analysis of these data resulted in a working hypothesis that planarity of the molecules is a prerequisite for their tuberculostatic activity (Orlewska et al., 2001).

Next, we showed that similar planarity was maintained in compounds lacking an H atom at N3, such as the dithioesters (formula B in the second scheme), due to conjugation and, except in thioesters (formula A), an intramolecular N—H···N contact was maintained between the same ortho N atom of the reversed pyridine (or pyrazine) ring as acceptor and the N5 amine group as donor. The overall planarity was lost only in the case of N2 substitution in an appropriate monoester (formula C in the second scheme) (Olczak et al., 2011).

The compounds described here represent both S-monothioesters [(E1) and (G1)] and S,S'-dithioesters [(F1) and (F2)] of heteroaroyldithiocarbazic acids (see third scheme and Figs. 1–4), in which an aryl-C(NH2)N– function present in the former study (Olczak et al., 2011) has been replaced by a 2-pyrazine-C(O)—NH– one. Thus, the compounds may be considered derivatives of the well known tuberculostatic pyrazinamid (first scheme). Despite the significant differences between these compounds and their amine analogues A, B and C (second scheme), we supposed that, due to the presence of an H atom at N3 in compounds (E1), (F1) and (F2), an analogous intramolecular hydrogen-bond contact will be formed as in the N—H heteroarylcarbamidoyl hydrazinium cation (compound A in the second scheme). As a result, the molecules should be planar and the compounds may show similar antibacterial activity.

In addition, we included in this study compound (G1) (with a methyl substituent at atom N2), which was unable to maintain planarity of the whole molecule due to spatial repulsion between this methyl group and the carbonyl groups (see second scheme). As the compound showed some tuberculostatic activity, it was important to examine changes in its molecular structure. The question concerning planarity could not be answered by simple inspection of the Cambridge Structural Database (CSD, Version?; Allen, 2002), as among about 20 structures comprising esters of heteroaroyldithiocarbazic acid, N2-substituted derivatives are not present. Structures in which the N atom is incorporated into the pyrazine or pyridine ring at the ortho position, thus playing an important role of acceptor in an N3—H···N(aryl) intramolecular hydrogen-bond contact, are similarly absent.

As we expected, the molecules of compounds (E1), (F1) and (F2) are planar except for the terminal ester group, while the molecule of (G1) shows a twist at N—N bond (Fig. 4) caused by spatial repulsion introduced by the methyl group at N2. Thus, we suppose that the main factor responsible for planarity is conjugation from the aryl ring to the thio group. Conjugation along the C1N2—N3—C4—C41 chain in (F1) and (F2), or the SC1—N2—N3—C4—C41 chain in (E1), is confirmed by both the values of the respective torsion angles in these fragments, all being close to 180°, and the shortening of the formally single bonds N3—C4 to 1.338 (2), 1.333 (2) and 1.322 (3) Å in the three independent molecules of (E1), 1.344 (2) Å in (F1), 1.341 (4) Å in (F2) and 1.342 (2) Å in (G1), and C4—C41 to 1.494 (3), 1.493 (2) and 1.498 (3) Å in (E1), 1.502 (2) in (F1), 1.497 (4) Å in (F2) and 1.499 (2) Å in (G1) (Table 5).

Due to the overall planarity of the molecules of (E1), (F1) and (F2), there are two short intramolecular hydrogen-bond contacts, both with the N3—H group as the donor (see second scheme and Tables 1–4). The first contact, N3—H..N(pyrazine), is observed in all compounds studied here having an N3—H group, including (G1). The H···N distances and N—H···N angles are in the ranges 2.21–2.28 Å and 107–110°, respectively (Table 6). Similar contacts are observed in N-substituted picolinamides found in the CSD, i.e. 2.15–2.32 Å and 100–116°. The other intramolecular contact is that of N3—H···S, with H···S distances between 2.42 and 2.55 Å, and N—H···S angles between 108 and 113° (Table 6). The values agree well with those found in similar molecules in the CSD (2.37–2.61 Å and 107–113°). The exception is structure (G1), in which substitution at atom N2 (see second scheme ) makes an intramolecular N3—H···S contact impossible.

There are some doubts concerning the structural significance of these contacts (Table 6), mostly due to the commonly accepted view that hydrogen bonds with D—H···A angles below 120° do not contribute substantially to the stabilization energy of the structure (Wood et al., 2009). However, the value of 120° refers to intermolecular hydrogen bonds, while in this study we are concerned with intramolecular systems. In the crystallographic literature, arrangements similar to that formed by the N3—H···N contact (i.e. five-membered ring motifs) were discussed by Bilton et al. (2000) and Galek et al. (2010), who found for them a probability of formation of over 70% and an average hydrogen-bond angle of only 109°. Less is known about N—H···S arrangements similar to those present in the structures described in this study. However, it seems from our data (Table 6), and from a couple of examples comprising a five-membered intramolecular N3—H···S motif which were found in the CSD, that N3—H···S contacts are geometrically less stressed than N3—H···N ones. In consequence, we believe that both the N3—H···N and N3—H···S close contacts observed in this study may be considered intramolecular resonance-assisted hydrogen bonds of some structural significance. The bonds aid conjugation along the main molecular chain to maintain planarity of the whole molecule, except for the terminal substituents of the ester group.

The molecular packing in (E1), (F1) and (F2) is determined mainly by their planarity (Fig. 1 and Figs. 5–6) and relatively weak intermolecular hydrogen bonds. In the diesters (F1) and (F2), there is only one weak C—H···O interaction in each structure. In (F1), C44—H···O5(x - 1, y, z) hydrogen bonds join the molecules into infinite C(7) chains parallel to the [100] direction, while in (F2) the molecules form dimers - R22(10) rings according to the graph-set definition of Bernstein et al. (1995) - through C46—H···O5(-x + 1, y, 3/2 - z) hydrogen bonds. In ester (E1), which comprises one hydrogen donor group, N2—H, and three independent molecules, the intermolecular interactions are more complicated. Molecules B and C are connected by N2B—H···O5C and N2C—H···O5B hydrogen bonds (Table 1), joining molecules into approximately coplanar dimers which form R22(10) rings. Molecules A and B are connected into asymmetric dimers (Fig. 1) by C44B—H···O5A and N2A—H···N45B hydrogen bonds, forming R22(8) rings. In the N'-methylated ester (G1), one weak intermolecular C43—H···O5 hydrogen bond is observed (Table 4). The bonds join the molecules into infinite C(6) chains running parallel to the [110] direction. In addition, an intermolecular N3—H3···S1 short contact may be considered a weak hydrogen bond (Fig. 7).

The terms tuberculostatic and antituberculostatic seem to have been used to mean the same thing. Please check and make consistent.

Experimental top

The syntheses of the title compounds were described by Foks et al. (2000) for (E1) and (F1), by Gobis, Foks, Zwolska & Augustynowicz-Kopeć (2006) for (G1), and by Gobis , Foks, Żuralska & Kędzia (2006) for (F2). Single crystals of compounds (E1), (F1), (F2) and (G1) suitable for X-ray diffraction were obtained from chloroform–ethanol (1:1 v/v), dioxane, ethanol and ethanol solutions, respectively, by slow evaporation of the solvents at room temperature.

Refinement top

H atoms were located in difference Fourier maps and subsequently geometrically optimized and allowed for as riding atoms, with C—H = 0.95 for aromatic CH groups, 0.97 for secondary CH2 groups and 0.96 Å for methyl groups, and N—H = 0.86 Å, with Uiso(H) = 1.2Ueq(C,N). For compound (G1), the precision of the Flack x parameter [Flack (1983); x = 0.18 (11)], whether calculated by the `hole-in-one' method or using TWIN/BASF in SHELXL97 (Sheldrick, 2008), indicated that the structure was correctly oriented with respect to the polar axis direction, but was too imprecise to rule out the possibility of partial inversion twinning. However, the value of the Hooft y parameter [Hooft et al. (2008); y = 0.20 (2)], certainly suggests that partial inversion twinning is present.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.

Experimental. CrysAlisPro, Oxford Diffraction Ltd., Version 1.171.33.66 (release 28-04-2010 CrysAlis171 .NET) (compiled Apr 28 2010,14:27:37) Empirical absorption correction using spherical harmonics, implemented in SCALE3 ABSPACK scaling algorithm.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
